As I understand it, DDE is a Microsoft method that allows interrupt driven
communication between participating programs on a Windows platform.

We use this successfully to "image enable" HP3000 applications.

Reflection terminal emulator acts as the 'client' and a Visual Basic program
acts as the Image fetch/display/print 'server'.

We issue DDE commands from the reflection client to the Image server by
echoing the commands directly from the HP3000. These commands are prefixed
by the Reflection escape sequence that caused reflection not to display the
following text, but to interpret it as a script command.

Works pretty well, and provides a seamless interface to the users.

Here is a snippet of code from within a Quick designer procedure that
initiates a DDE session with a named server:-

       let CMD = 'dde-initiate "OLEImage" "OLEImage" V5'
       let CMD = "echo " + ESC + "&oF" + trunc(CMD) + CR
       run command CMD

ESC is the escape char, and CR is the Carriage return.

Neil

Hi all,

Is there a way to do DDE pokes and peeks from the HP to a Shared DDE
application across an NT network?

TIA
